  • Method for asynchronous population of data caches used with mass storage devices
    Patent number: 9442859
    Abstract: A method and system for transferring data from mass storage devices to the high speed data cache in a manner that imposes minimal overhead to the normal input/output mechanism and minimizes the load placed on the device being cached is disclosed herein. Minimizing the load placed on the slower device and minimizing the overhead of processing input/output requests results in optimal performance.

  • Method for the use of process identifiers to invalidate cached data in environments that allow processes to migrate between physical machines
    Patent number: 9164909
    Abstract: A method for utilizing process identifiers to invalidate cached data is disclosed herein. The invention is a method for associating persistently stored data with an identifier of the process which created it, such that when the process that created the data is no longer present on the machine where the data is stored the data may be marked as invalid to prevent the use of “stale” data.

  • Method for the use of shadow ghost lists to prevent excessive wear on FLASH based cache devices
    Patent number: 9104552
    Abstract: The present invention is a system and method for utilizing shadow/ghost list to prevent excessive wear on FLASH based cache devices. The method determines when data is highly likely to be accessed again, and avoids writes to a FLASH based caching device when data is unlikely to be accessed again through the use of “shadow” or “ghost” lists that are also used to perform adaptive caching.

  • Method for translating virtual storage device addresses to physical storage device addresses in a proprietary virtualization hypervisor
    Patent number: 8504757
    Abstract: A method to translate virtual storage device addresses to physical storage device addresses without the cooperation of the proprietary virtualization hypervisor is disclosed herein. The method of the present invention allows additional functionality to be added to the I/O processing of a closed/proprietary virtualization hypervisor by third party software or physical storage devices on the basis of individual virtual storage devices.
